PATENT MARSHALL ROMEO BOLES AND ARTHUR JOSEPH SNAVELY. OF FOUNTAN CTY.

' TENNESSEE.

COIL BOX.

Application ed March 9, 1925.

T all whom it may concern.'

Be it known that we, MARSHALL R. Boans and ARTHUR JosErH SNAVELY, citizens of the United States, residing at Fountain City, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Coil Boxes, of which the following is a specification.

This invention relates to improvements in internal combustion engines, the general object of the invention being to provide means whereby the coils of the ignition system of the engine are located above the engine so that the coils will be kept dry from the heat of the engine and from the circulating air from the fan and the coils can be wired to the various parts with less wire.

Another object of the invention is to provide means for holding the coils against movement in the supporting means and to provide means for making the coils readily accessible. I

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

ln describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a partial view of a motor showing our invention in use.

Figure 2 is a view of the coil supporting device with the cover thereof removed to show the coils in position.

Figure 3 is an end view.

Figure 4 is a section on line 4 4 of Figure 2.

Figure 5 is a section on line 5-5 of Figure 3.

Figure G is a section on line 6 6 of Figure Figure 7 is a perspective vieu7 of one of the terminal members.

Figure 8 is a partial sectional view of such member showing the same connected with the post and with the Wire.

Figure 9 is a fragmentary view of one of the coils.

1n these `views, l indicates a casing which Serial No. 14,274.

has the U-shaped legs 2 fastened to its body, theselegs being adapted to be fastened to the head of a motor A by means ot' some ot' the bolts t which fasten the head to the block. Thus the casing is supported above the head. One side of the casing is lett open and lthis side is adapted to belcloscd by a hinged cover 8 which is hinged to a strip 4 connected to the brackets 5 which are also adapted to be fastened to the head by some of the bolts ai. rlie ends of the casing 1 are provided with extensions 1, the outer and top edges of which are adapted to be engaged by the cover 3 when the same is in closed position. These extensions 1 are so formed that spaces 6 are left at the ends of the casing, when the cover 8 is in closed position, so that the air from the fan of the motor can circulate through the device and come in contact with the coils supported therein to keep the same free from moisture. The amount of air passing through the device can be regulated through means of the slide 't' at the front end of vthe casing which is adjustably held in'position by means of the nuts and bolts 8, the bolts passing through slots 9 in the slide. The cover is held in closed position by the latch 10. The casing is divided into four chambers by the partitions 11, each chamber receiving a coil B and the coils are held in the chambers by the turn buttons 12 pivoted to the outer edges of the partition. Blocks 18 are fastened to the upper portions of the partitions for engaging the upper ends of the coils for holding the coils against movement in the chambers. A strip 14 of metal is placed in a longitudinal groove 15 formed in the botto-m of the casing and this strip is connected with the binding post 16 which receives a conductor leading from the switch ofthe ignition system. Spring contacts 17 are fastened to this strip and these contacts are adapted to engage the contacts 7 placed on the bottom of the coils, each member 17 having a beveled part 17 so that the contact will be depressed as the coil is slid into the chamber and thus automatically engage the Contact b. A hole 18 is formed in the front of the casing through which the Wires 19 for connecting the terminals b of the coils to the timer pass. The conductors 20 lead from the terminals b of the coils to the spark plugs, these Wires passing over the outer edge of the bottom of the casing through the space between said edge and the cover 3 to the spark plug.

A lamp socket 2l is carried hy the rear end of the easing for receiving a small lamp which can be used to illuminate the interior of the device so that the parts therein can be easily seen at night or on dark days. The conductor wires for this lamp are shown at 22.

`We prefer to use a terminal clip, such as shown at 23, in Figures T and 8, for connecting the Wire to the terminal, this clip being formed of spring metal with a loop at one end to receive .a bent part at the other end, the parts of the loop and the part Q5 being provided with holes to receive the terminal post, shown in Figure 8. 'lhe tendency of the limbs of the clip will hold the edges of the holes in firm engagement with the post. rl`he conductor Wire is adapted to be soldered or otherwise fastened to the top of the clip.

l1 rom the foregoing it will be seen that we have provided a easing for the coils which is fastened tothe top of the engine and is so formed that the coils and their conductors will be subjected to the heat from the engine and to the air from the fan. Thus the coils and the Wires Will be kept free of moisture and but a small amount of Wire is necessary to make the connections. It also eliminates the use of porcelain or other insulators, such as are used Where the Wires pass throughlthe dash board. Broken circuits or the like are more readily found and are more easily remedied in this arrangement than in the old style arrangement of placing the coils on the dash. The parts can be easily examined and by throwing the cover 3 down it Will act as a support for tools and the like. By firmly fastening the coils in the chambers all movement of the coils is prevented so that the contacts are in iirm engagement at all times. The lamp permits the parts to be illuminated at night.

It is thought from the foregoing description that the advantages and novel features of the invention Will be readily apparent.

We desire it to be understood that We may make changes in the construction and in the con'ibination and arrangement -of the several parts, provided that such changes fall Within the scope of the appended claims.

What We claim is l. In an internal combustion engine, a coil box, means for fastening the saine to the top of the engine so that coils in the box will be subjected to the heat from the engine and the ends of the box having openings therein through which the air from the fan will pass.

2. ln an internal combustion motor. a coil casing, partit-ions therein dividing the same into coil receiving chambers, means i'or detachably holding the coils in the chambers, legs connected with the bottoni of the casing and adapted to be attached to the top of the engine by the top bolts and a hinged cover connected with a part of the engine top and arranged to cover one side of the casing.

3. ln an internal combustion motor, a casing having one side open, extensions at the ends extending beyond the open side, partitions dividing the casing into coil receiving chambers, means Yfor detachably holding the coils in the chambers, means for preventing movement of the coils in the chambers, legs connected with the bottom of the casing and adapted to be fastened to the engine top by the bolts of said top, a strip adapted to be bolted to the engine top, a cover hinged to said strip for closing the open side of the casing, said cover engaging the end extensions, a slide vertically adjustable on the front end of the casing for controlling the passage of air under the casing and into the space formed by the cover and the extensions.

4L. In an internal combustion motor, a coil casing, means for fastening the same to an engine top, means for holding coils in the casing, a hinged part for the easing, a lamp for illuminating the cas-ing, a contact strip in the bottom of the easing, spring contacts thereon for engaging the bottom contacts of the coils, electric connections for the lamp and coils and means for controlling the passage of air from the fan through the casing.

In testimony whereof We affix our signatures.
